Generic non-repudiation protocols supporting transparent off-line TTP

Guilin Wang, Jianying Zhou, Meng-Chow Kang
2006 Journal of Computer Security  
In this paper, we first argue that it is really meaningful in practice to exploit generic fair nonrepudiation protocols with transparent off-line trusted third party (TTP).  ...  Namely, in those protocols, each involved party could use any secure digital signature algorithm to produce non-repudiation evidences; and the issued evidences are the same regardless of whether the TTP  ...  Acknowledgements The author would like to thank all anonymous referees, on behalf of IWAP 2005 and Journal of Computer Security, for their very helpful and detailed comments on the protocol, as well as  ...

Generic, Optimistic, and Efficient Schemes for Fair Certified Email Delivery [chapter]

Guilin Wang, Feng Bao, Kenji Imamoto, Kouichi Sakurai
2005 Lecture Notes in Computer Science  
Then, we present two generic optimistic certified email schemes with transparent TTP.  ...  Our schemes are not only fair, but also support timeliness in two flavors: one scheme supports weak timeliness but with stateless TTP, while the other guarantees (strong) timeliness though only supports  ...  Specifically, our schemes overcome the security shortcoming in schemes [9, 14] ; support transparent TTP while the schemes in [10, 12] do not; provide evidences for non-repudiation of origin while the  ...

We could, thus, recall the following definitions related to non-repudiation protocols: Definition 2 (Non-repudiation of Origin NRO).  ...  A protocol provides a non-repudiation of origin service if, and only if, it generates evidence of origin which will allow the recipient to demonstrate to an arbiter whether the originator was or not the  ...  A TTP is said to be on-line if it acts in all protocol executions. Definition 13 (Off-line TTP).  ...

Then it describes the general multiparty non-repudiation problem, and analyzes the state-of-the-art mechanisms.  ...  Actually, it represents the core of a non-repudiation protocol. It is greatly influenced by the communication channel properties.  ...  A TTP may also generate and provide supporting evidence in a non-repudiation service.  ...

An intensive survey of fair non-repudiation protocols

Steve Kremer, Olivier Markowitch, Jianying Zhou
2002 Computer Communications  
Therefore a fair non-repudiation protocol has to generate non-repudiation of origin evidences intended to Bob, and non-repudiation of receipt evidences destined to Alice.  ...  In this paper, we clearly define the properties a fair non-repudiation protocol must respect, and give a survey of the most important non-repudiation protocols without and with trusted third party (TTP  ...  This approach, using an off-line TTP, is also called the optimistic approach.  ...

Risk Balance in Optimistic Non-repudiation Protocols [chapter]

Mohammad Torabi Dashti, Jan Cederquist, Yanjing Wang
2012 Lecture Notes in Computer Science  
We investigate how the behaviors of malicious trusted parties affect participants of optimistic non-repudiation protocols. We introduce a notion of risk balance for exchange protocols.  ...  As a case study, we investigate the consequences of malicious behaviors of trusted parties in the context of two fair non-repudiation protocols, proposed by Gürgens, Rudolph and Vogt (2005) .  ...  An off-line trusted third party (TTP) supervises the exchanges. If the participants correctly follow the protocol, the TTP does not intervene in the exchange.  ...
